I have a JPanel that contains two JComponents, say two JButtons, btnLeft and btnRight. I want these two buttons aligned horizontally and I want btnLeft to be on the left side of the JPanel and btnRight to be on the right side of the JPanel with whatever space is left over in between.

I know I can do this with a BoxLayout by adding a horizontal strut in which I have to specify the amount of space in between, but there must be a simpler way without having to specify what the left-over space in between is.
